RFC9457 implementation for Python
rfc9457 is a set of exceptions to support easy error management and responses
in web based apis.
Each exception easily marshals to JSON based on the RFC9457 spec for use in api errors.
This library is currently used to support problem details in both Starlette and FastAPI.

Custom Errors
Subclassing the convenience classes provides a simple way to consistently raise the same error with details/extras changing based on the raised context.
from rfc9457 import NotFoundProblem
class UserNotFoundError(NotFoundProblem):
title = "User not found."
UserNotFoundError(
detail="details",
custom_key="value",
).marshal()
{
"type": "user-not-found",
"title": "User not found",
"status": 404,
"detail": "details",
"custom_key": "value",
}
